Cat-Back Exhaust

aFe is proud to introduce an all new MACH Force-Xp cat-back exhaust system for the 2015-2017 Ford Mustang with the V6-3.7L or V8-5.0L engine. In testing, this system resulted in gains up to +12 horsepower and +10 lbs. x Ft. of torque verified by our in house dyno. This cat-back exhaust system utilizes full 3" tubing with reduction tubes to fit the OE connections. Remove them and combine with the aFe power Twisted Steel Long tube headers and connect ion pipes (48-33012-YC) for added flow and performance. This system incorporates dual, high-flow mufflers to improve performance across the power band while maintaining an aggressive sound. aFe also added an X-pipe with resonators to balance and evenly distribute exhaust pulses traveling through the exhaust system, creating more efficient flow and better performance while minimizing exhaust drone resulting in an awesome sound. To finish off the exhaust, dual 4" high-luster polished 304 stainless steel tips are included. This is a direct bolt-on system no modifications necessary and includes necessary hardware for a hassle-free installation. Aggressive Sound: Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. X-Pipe with Resonators Balance Tube: The equalizer balance tube evenly distributes exhaust pulses traveling through the exhaust system. This creates a more efficient flow for better performance while minimizing exhaust drone. Simple Installation: This is a direct bolt-on system which retains your factory exhaust tips and includes necessary hardware for a hassle-free installation. No modifications necessary. Leak-Free Seal: High quality band clamps are used for a complete 360 degree sealing surface. Dual 304 SS Tips: Finishing off this unique exhaust system are dual, aFe laser etched, 4" polished 304 stainless steel tips for an aggressive style.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
